Semantic Web service is becoming a new paradigm for distributed computing over the Internet. This gives the power to applications to automatically or semi-automatically discover, invoke, compose and monitor web services. The success of semantic web service depends on how we can find web services that satisfy user needs.
Many approaches have been proposed for service discovery. Most of them utilizing Ontology to describe web service related information. However, in Ontology based approaches it is still difficult to focus the search on specific attribute of the service. In this research, Web Service Description Language (WSDL) of web service is represented as WDAG. With this representation, users can dynamically change attribute's weight to refine the search. For example, user can assign a bigger weight to 'input name' attribute than other attributes to relatively focus on the attribute in search.
